Claims.

The invention relates generally to the art of manufacturing containers formed in whole or in part of paper, and it primarily seeks to provide a novel apparatus for applying to the ends of the container bodies the adhesive employed to form an adhesive union or seal between the body ends and the end closures which are attached thereto in completing the containers.

In the manufacture of paper containers, the cylindriform paper shells or container bodies have their ends closed by paper or metal end closures usually shaped to include an annular channel in which to receive an end of the container body. It is customary to effect an adhesive union between the container bodies and the applied end closures, this union or seal being eiiected in some cases by an adhesive applied at the end edge only on the container body, in other cases by an adhesive applied at said end edge and also over a limited distance on the adjacent inner wall of the container body, in other cases by an adhesive applied at said end edge and also over a limited distance on the adjacent outer wall of the container body, and in some cases by an adhesive applied at said end edge and also over a limited distance along both the inner and outer wall portions of the container body adjacent said end. It is an object of the present invention to provide a novel apparatus for rapidly and efiiciently applying adhesive to container bodies of various heights and diameters in any of the positions aforesaid.

In its more detailed nature the invention seeks to provide a novel apparatus of the character stated in which the can bodies are rolled along between two endless belts while the adhesive is applied to the ends thereof by contact with a rotating applicator roll.

Another object of the invention is to provide an apparatus of the character stated in which there are included tracks for supporting and guiding the container bodies as they are rolled along by the belts, said tracks and said belts being mounted for adjustment so that the apparatus can be adapted for handling bodies of varied heights and diameters.

Another object of the invention is to provide in an apparatus of the character stated an adhesive applying means comprising the applicator roll and means for supplying adhesive to the surface of the roll, and means to move the roll toward or from the path of travel of the bodies to position it for cooperation with bodies of various heights.

Another object of the invention is to provide in an apparatus of the character stated means for adjustably mounting the applicator roll with its axis parallel the path of travel of the bodies andso that said axis can be adjusted as to position to lie at, above or below the center of the wall thicknessend extremity contacted by the roll.

Another object of the invention is to provide in an apparatus of the character stated a pick-up roll for picking up the adhesive and applying it to the applicator roll, and novel means for adjusting the position of the pick-up roll so as to vary its spaced relation to the applicator roll.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more fully understood by following the detailed description, the appended claims and the several views illustrated in the accompanying drawings,

In the drawings,

Figure 1 is a front elevation illustrating an apparatus embodying the invention.

Figure 2 is a plan view illustrating the apparatus shown in Figure 1.

Figure 3 is a right hand elevation illustrating the apparatus shown in Figure 1.

Figure 4 is a vertical cross section taken on the line 6-4 as indicated on Figure 1 and on Figure 2.

Figure 5 is a fragmentary vertical cross section taken through the bearings for the pick-up and applicator rolls at one side of the apparatus.

Figure 6 is a fragmentary vertical longitudinal section taken on the line 6-6 on Figure 3.

Figure 'I is a diagrammatic cross sectional view illustrating the cooperative relation between an end of a container body to which adhesive is being applied. and the applicator roll, three positions of adjustment of said roll being illustrated.

The apparatus herein illustrated as an example of embodiment of the invention, includes a supporting frame 5 whereon is mounted a table -6. End uprights 1 are secured as at 8 on the table 6, and each thereof carries an upper extension piece 9 which is vertically-adjustably secured thereon as at It],

The uprights 1 are equipped with bearings H in which two shafts 62 are rotatabl mounted, and two shafts i3 are similarly mounted in bearings l6 carried by the extension piece 9., Pulleys l5 are fixed on the two shafts l2, and similar pulleys I 6 are fixed on the two shafts l3. An endless belt ll passes over the two pulleys i5, and an endless belt 38 passes over the two pulleys 16. See Figures 1, 2 and 4 of the drawings.

Intermediate brackets I I are secured as at 20 on the table I between the uprights I, and each thereof has, an adjustable horizontal supporting leg portion 2| for supporting a pair of parallel spaced tracks 22. It will be obvious by reference to Figures 1, 3 and i of the drawings that the upper surfaces of the tracks serve as support guides for the cylindriform container bodies 23 which are given a progressive rolling movement by the upper and lower engaging flights of the belts i1 and it which move relatively, in the manner indicated by the arrows on Figure l, and at diiferential speeds by reason of driving devices later to be described. The standard I also serves to support a track or guide 24 disposed to engage the ends of the rolling container bodies 23 in the manner clearly illustrated in Figures 2, 3 and 4 of the drawings.

The cylindriform container bodies 23 are fed into the apparatus by inclined guideways 2! under control of a single delivery or spacer star 28 which may be driven by any suitable means (not shown). It will be obvious that each time a finger of the wheel 28 moves to release the lowermost container body 23, the next succeeding finger-will intercept the gravitating line oi container bodies and hold them for an interval suflicient to allow the released container body to move between the cooperating fl ghts of the belts l1 and I8 in properly spaced relation to the last released container body and the container bodies in the feed-in runway 25.

A small sprocket 21 is mounted on one of the upper shafts I! and i driven by a chain 28 which also passes over a large sprocket 29 mounted on the underlying lower shaft ii. The shaft I2 is drivenlthrough a bevel gear couple 30 by a power shaft ll which has rotative bearing in the standare! 22 which is secured as at 22 on the table 8. It will thus be apparent that, the belts l1 and I 8 are positively driven by the power shaft 8!, the upper belt I! being driven more rapidly than the lower belt II. By reason of the fact that the container body engaging flight of the belt I! moves more rapidly toward the left. as viewed in Figure 1, than the cooperating flight of the lower belt l1 moves toward the right, progressive rolling movement toward the left will be imparted to the container bodies 22 as herelnabove stated.

An applicator roll ll is provided and is disposed in the manner clearly illustrated in Figures 2 and 4 of the drawings with its axis disposed approximately at the level of the upper surfaces of the tracks 22 and paralleling said tracks. The roll I4 has trunnion hearing as at ll in slide blocks 2! which are vertically slidable in guideways 21 provided in the bearing block ll. See Figures 1, 2, 3, and 6. The bearing blocks is are adjustably slidable as at 29 on dove tail rails ll on which said blocks areadjustably secured by clamp screws II in the manner best illustrated in Figure 5. It will be noted that the screws 4| pass through longitu al slots 42 in the rails it.

A screw II is se ed to and projects upwardly from each slide block it, and each screw is threadably engaged by a captive sleeve It. It will be obvious that by rotating a sleeve II, the corresponding slide block 38 may be lifted or lowered so as to vertically adjust the relation of assacu nion bearing as at ll in two eccentrics 41 which are rotatably-adjustably mounted as at {I in the bearing blocks 38. The outer flange extension ll of each eccentric is provided with an arcuate slot It in the manner best illustrated in Figure 3. A securing screw 5i passes through each slot II and is threaded into the respective block 3| so that it can be utilized to secure adjustment of the respective eccentric bearing member 41. A crank 52 is secured to each eccentric bearing member 41, and it will be obvious that by loosening the screws 51 and manipulating the crank 52, the eccentric bearing member 41 can be rotated about their common axis so as to efl'ect an adjustment of the position in space of the pickup roll 45, thereby to adjust the spaced relation between the axis of the pickup and applicator rolls. It'will be obvious that the pickup roll will be suitably adjusted after each adjustment of the applicator roll, but the position of the pickup roll may also be adjusted to vary the spacing between the rolls and, the amount of adhesive which will be applied by the pickup roll to the applicator roll.

The bottom portion of the pickup roll I! rotates in a suitable adhesive 52 in a reservoir or tank 54 which is supported on the bearing blocks 38 in the manner clearly illustrated in Figures 1 and 2 of the drawings. A proper level of adhesive is maintained in the reservoir it by the usual inverted bottle equipment 55. It will also be apparent by reference to Figures 3 and 4 of the drawings that a scraper 58 is adjustably mounted in position for having an edge portion thereof lying close to the outer surface of the pickup roll l! in a manner for controlling the amount of adhesive to be carried upward by said roll surface into position for contacting with the applicator roll 3|.

A lug 5! depends from the tank or reservoir H, and a captive screw 58 is secured to said lug and is threaded through a bracket I8 which is secured to the table 6. A hand wheel 60 is mounted on the outer end of the screw 58, and it will be obvious that by rotating the wheel 80, movement of the reservoir 64 and the rolls l5 and. supported thereon toward and from the container body supporting trackways 22 can be effected. It will be apparent by reference to Figure 4 that the upper and lower belts l8, II, the supporting trackways 22, the guide rail 24 and the surface of the applicator roll 34 engage thev container bodies 23 peripherally and at the ends so as to accurately guide them as they are being progressively rolled along by conveyor belt flight contact in the manner clearly illustrated in Figure 1. By adjusting the hand wheel 80, the spaced relation of the guide rail 24 and the adjacent surface of the applicator roll at can be varied so as to adapt the machine for operating upon container bodies of various heights. The spacing of the supporting rails'22 can be altered for the same purpose. It will also be obvious that by vertically adjusting the extension pieces9 the spaced relation of the conveyor belts l1 and it can be altered so as to adapt the apparatus for work upon container bodies of various diameters.

A small sprocket BI is mounted upon the applicator roll shaft 35 and has rotation, imparted thereto by a chain 62 which also passes over-a small sprocket 53 which is rotatable about a stud shaft 64 secured'to the table, said sprocket ll being secured to and rotatable with a large sprocket l5 also-rotatable about the stud shaft N and driven by a chain I6 which passes thereover and over a small sprocket Bl mounted on the power shaft 3 l As each container body is released by operation of the star wheel 26, it rolls down the inclined guideways 25 and is received between the cooperating flights of the endless conveyor belt ll, Ill. The container bodies are progressively rolled in spaced relation in the manner hereinbeiore described, and while being so rolled have adhesive applied to the ends thereof by the applicator roll 34. After each container has had adhesive applied to the end thereof, in the desired manner,

it passes out from between the conveyor belts ll,

l8 into the receiving end of an inclined feedway guide 68. The guide 88 may takethe form of the well known twist guide which is effective to turn the container a quarter turn, or a greater amount, and deliver the same to a storage place or to other apparatus.

It is an object of the invention to provide an apparatus of the character described which may be adapted for applying adhesive to container bodies of different heights and diameters, and by reason of the vertical adjustment of the applicator roll 3t, it is also possible to apply adhesive to the endof the container body and a portion of the interior adjacent the end, to the end of the container body and a portion of the exterior adjacent said end, or to the end of the container body and to a portion of both the inner and outer walls thereof adjacent said end.

In Figure 7 of the drawings three adjusted positions of the applicator roll are diagrammatically illustrated. When the axis of the roll is positioned at A, the full line position in Figure '7, the viscosity of the liquid adhesive, the surface tension therein, and the draggingthereof off the rotating applicator roll surface will cause the adhesive to be directly applied to the end extremity of the container body and also to run a limited distance along the outer surface of the container body and also to be dragged off the roll and 11111 a limited distance along the inner wall of said body. When the roll 36 is lowered to the dotted line position B, illustrated in Figure '7, the adhesive will be applied to the end extremity of the container body 23 and will run a limited distance along the external surface of said body. When the applicator roll 36 is lifted to the dot and dash line position C, adhesive will be applied to the end extremity of the container body 23 and will run a limited distance along the inner wall portion adjacent said end extremity.

It is to be understood that the details of construction of the cooperating parts can be variously changed without departing from the spirit and scope of the invention as deflned' in the appended claims.
